RUNNING-GEAR FOR VEHICLES.

To all whom it may concern:

Be it known that I, JESSE H. HAND, a citizen of the United States,residing at Ann Arbor, county of Washtenaw, State of which it pertainsto make and use the same,

reference being had to the accompanying drawmgs, which form a part ofthis specification. 1

This invention relates to running gear for vehicles.

It has for its object an improved means of suspending the vehiclerunning gear on the wheels, animproved means of mounting the wheels toenable the vehicle runninggear to be turned or guided.

In the drawings :Figure 1, is a plan view. Fig. 2, is a side elevation.Fig. 3, is a cross section through the vehicle frame. Fig. 4, is aperspective of the axle box housing.

Fig. 5, is a perspective of the connection between the steer-post andthe steering bars.

Fig. 6, is a cross section of the axle box housing.

The mam frame is rectangular and rigid;

at the front are two pivoted sub-frames, at

the rear a singlesub-frame rigidly connected to the main frame.

1 and 2 indicate the longitudinal side bars ofthe main frame.

3 and 4 indicate the cross members at the rear and front endsrespectively. At the rear the cross member 3 is extended on each sidebeyond the bars 1 and 2 and is supple mented by cross members 5, whichextend equally with cross member 3. The projecting ends of cross members3 and 5 support spring bars made in the form of half elliptic springs 16and 17 on the left side and 16 and 17 on the right side, which aresuspended by shackles and brackets, from which rise the axle boxhousings 18 and 19 on the left hand and 18 and 19 on the right hand. Onthe right side at the rear of the main frame spring members 7 and 8support a vertical guide 10*, between whose upright members engages asliding axle bearing 9. Between the upper side of the axle bearing 9 andthe cross bar 40 which unites the uprights is a Specification of LettersPatent.

Serial No. 442,447.

spiral spring 11; in the axle bearing 9, and its companion bearing whichis supported by the cross bar 40*, is the axle of the rear right wheel31. A similar suspended spring framework, comprising the spring bars 7,8, with parallel upright guides and cross bars 40 40, support thebearings for the axle of wheel 30.

At the front end the right hand wheel 14 is journaled in axle boxeswhich are supported by side springs 16 ,17 these springs are suspendedby brackets and shackles from a sub-frame whose main member, 15*, isarched around the pivot 42 as a center; the axle of wheel 14 is short,and the entire frame which supports the wheel is adapted to change itsangular relation to the main frame. 'lhe wheel 13 at the left front ofthe frame is supported in a similar pivoted subframe through the mediumof the side springs 16 and 17. 'lhe cross bars of the axle box housingsof both front wheels are seenin Figs. 2 and 3 at 11 11,11 and 11 and thehousing 10 of the wheel 14 is seen in elevation in Fig. 2. lhe archedmembers 15, 15 of the two sub-frames at the front of the vehicle areprovided with rack segments and mesh with a pinion 24. 'lhe pinion isactuated by post 29 with which it is connected by a universal joint 29*.'lhe sub-frames at the front swing under the main frame against whichthey bear with interposed antifriction rollers. 21, 22 indicate therollers over the right hand frame and 21 and 22. those over the lefthand frame; they swing over the cross bar member 20 with inter osedantifriction rollers 23 and 23.

At the center of the rear axle 9 is shown the gear housing 32 withinwhich the actuation due to the rotation of the main shaft of the engineis communicated to the axle 9, which is the driving axle.

What I claim is 1. A vehicle running gear, having in combination a rigidrectangular frame, a subframe for each wheel, journal bearings for eachwheel at both sides thereof, said independent journal bearings beingmounted on independent spring suspension devices.

2. In a vehicle running gear, in combination with a rigid rectangularframe, a subframe pivotally connected therewith, a wheel havingindependent journal bearings at each side thereof mounted in saidsub-frame, and independent-spring supports for each journal bearing,substantially as described.

3. 1n a vehicle running gear, '111 combination with a main frame, a pairof sub-frames independently pivotally connected to said main frame,journal bearings sup orted by each of said sub-frames on each si ethereof, independent spring suspension members 10 therefor, a Wheelsupported by each pair of said journal bearings, and means forsimultaneously oscillating the sub-frames, substantially as described.

In testimony whereof, I sign this specification in the presence of twoWitnesses.
